Audio Research 300.2 Power Amp

Excellent condition with original double box and manual. Powerful enough for pretty much ANY speaker out there.

Delivering a robust 300 WPC into 8 ohms and conservative 500 WPC into 4 ohms, the 300.2 will satisfy the need for high power by the most demanding music listener.

The 300.2 has the same connectivity as the 150.2, with switchable BAL and SE inputs, gold-plated brass binding posts, 12V trigger, and a detachable 14 gauge A.C. power cord. Physically, the 300.2 is one inch taller than a 150.2, and the front panel is thicker - the same as on a Ref 2. Handles are available for US$80.00 per pair.

The 300.2 maintains the same engaging musical profile as the 150.2, with remarkable purity, a grainless transparency, vivid sound staging, and great dynamics. The bonus is that the 300.2 provides additional weight and authority and a greater sense of ease. Except for its siblings, the 150.2 and 150M, the 300.2 sounds unlike any other amplifier because it marries the best musically-involving qualities of great tube designs with the authority and control of the best solid state designs, easily handling the toughest loads or the most inefficient speakers without strain. And, with its high efficiency, the 300.2 produces little heat, making it perfect for in-cabinet installations. When you hear this amplifier you will appreciate what a great value it represents.

From The Absolute Sound review:

Because the ARC sounds so expressive and full of life, it is more engaging on an emotional level than most other amplifiers. Instead of presenting “good sound” in a vacuum, the 300.2 gives listeners the sense of participating in musical conversations. In that context, the ARC’s ability to convey emotional content makes all the difference.
